21.5'' Outdoor Air-Cooled Digital Display – Sunlight Readable, IP65, 2500 nits | RisingStar

Outdoor environments demand a display solution that maintains visibility, stability, and performance under direct sunlight, heat, dust, moisture, and continuous operation. The RisingStar 21.5-inch Outdoor Air-Cooled Digital Display is engineered precisely for these conditions. Designed with industrial-grade components, a 2500-nits high-brightness panel, intelligent thermal management, and IP65-level protection, this display ensures reliable 24/7 operation for smart city systems, transportation hubs, EV charging stations, fuel dispensers, outdoor kiosks, and digital-out-of-home (DOOH) advertising.

This product combines energy efficiency, long lifecycle, high contrast performance, the latest backlight technologies, and ultra-wide viewing angles, making it one of the most durable and cost-effective outdoor digital signage solutions in its category.

Why Outdoor High-Brightness Displays Matter Today

According to industry research (summaries from DOOH and digital signage market studies):

• The global outdoor digital signage market is projected to grow continuously due to the rapid expansion of smart cities, EV charging networks, transportation IoT systems, and DOOH advertising.

• High brightness and reliability have become the most critical purchasing factors.

• Displays between 21.5–32 inches remain the most deployed sizes in charging stations, kiosks, and transit information terminals.

Outdoor displays must withstand temperature fluctuations, direct UV exposure, rain, pollution, and long operational hours. The RisingStar 21.5-inch platform is built to meet these evolving market requirements.

Key Features

High Brightness 2500 nits – Sunlight Readable Performance

The industrial-grade LED backlight delivers 2500 nits, ensuring clear, vivid content even under direct sunlight. A built-in ambient light sensor automatically adjusts brightness to reduce energy consumption and extend backlight life.

Air-Cooled Thermal System – Engineered for Long Outdoor Operation

RisingStar’s optimized air-cooled architecture maintains internal temperature stability without the added complexity and maintenance cost of liquid-cooling systems.
Benefits include:

• Lower maintenance frequency

• Lower power consumption

• Higher long-term system reliability

• Silent and efficient airflow design

This thermal solution allows stable operation between –20°C to +70°C, making it ideal for harsh outdoor climates.

LCD Blacking Defect Prevention

Heat-induced LCD blackening is a major challenge for outdoor screens. RisingStar integrates special panel technology that ensures zero blackening defects, even under strong sunlight and elevated temperatures.

Industrial Durability – IP65 Protection & 5mm Tempered Glass

The front side of the display is sealed to IP65, offering strong protection against:

• Rain

• Dust

• Moisture

• Vandalism (with optional IK reinforced glass)

The 5mm tempered cover glass maximizes outdoor robustness without compromising optical clarity.

Wide Viewing Angle 178°/178°

Perfect visibility from all directions, ensuring clear viewing for public-facing signage and passenger information systems.

Low Power, Low Heat, Long Lifecycle

• Energy-efficient LED backlight

• 50,000-hour backlight lifetime (MTBF)

• Optimized power design keeps internal temperature consistently low, improving durability and reducing total cost of ownership (TCO)
